r v dd anovidm Each of into the chamber or space above the diaphragm or plate 7 to pass through the discharge slots or openings 4.

The supplemental of pilot burner com prises an elongated casing or body 11 of diamondshaped cross section, and fitting within one of'the furrows or depression 3. A series of slots or kerfs 12 are cut or sawed in the ridgeof the casting or body 11 to provide outlets for the gaseous mixture introduced into the body or casing 11.

A diaphragm or partition plate 13, which it iS elongated, is. fitted between the Sides of the body or casing 11, and the outer or forward end of the body or casing ll, has an inwardly projecting mixing tube 14, ex-

tending below the diaphragm or'plate 13, 1 the diaphragm or plate 13 being apertured,

as clearly seenin Fig. 4.

The generators or retorts for the main and auxiliary burners, embody supply pipes] 15 and 16, respectively, which are connected to any suitable source of liquid fuel, and

A operate with which extendlongitudinally over the auxiliary or pilot burner and the 'correspondlng valley 3 of the main burner. Rods 17 are preferably extended throughthe generator or retort portions of the'pipes 15 and 16, which are disposed above the main and auxiliary' burners, whereby the rods 17 facilitate the generation of the vapor or the evap+ orization of the liquid fuel.

The forward or outward ends of thetubes 15 and 16 are downturned or deflexed, as at 18 and 19, respectively, and cruciform valve casings 20 and 21 have their upper arms engaged to the respective depending angular ends 18 and 19 of the supply or generator pipes. The. inwardlyprojecting arms 22 arid23 of the cruciform valve casings 20 and 21, respectively, are in the. form ofnozzles PI'OJGCtlIlg into the mouths or outer ends of the respective mixing tubes 10 and 11, while needlevalves 24 are threadedly or adjustably'engaged through the outwardly projectingfarms ofthe casings 20 and 21, to cothe outlet apertures or ducts ofthe nozzles 22 and 23 for controlling the discharge of ing tubes.

In practice, the present device may be readily applied to the the box of a cooking or heating stove, or to other structures to be heated. In starting the burner, the fuel is first admittedinto the supply and generator pipe 16 of the auxiliary or pilot burner, and the generationof the, vapor may be started by heating the pipe 16 in any suitable manner. The evap'orized fuel may then be discharged into the mixing tube 14 of the auxiliary'or pilot burner, by properly controllin the corresponding needle valve 24. As the vaporized fuel is injected into the body or casting 11 of the auxiliary or secondary burner, air will be drawn into vapor into the respective mix- 1 w1th the drawmg, the other advantages and the mixing tube 14: to commingle with. the fuel, the air and fuel being thoroughly mixed and spread under the diaphragm or partition 13, as will be obvious, and the mixture will rise through the apertures in the diaphragm 13 throughout the length of the same. The mixture will then pass outwardly through the slots or. outlets 12 for supporting the pilot flames, which will heat,

both of the pipes 15and 16 for continuing the generation of the vapor within the pipe 16, and for starting the generation of the vapor within the main pipe 15 when the fuel is admitted thereinto. Then, as the fuel is admitted into the main pipe 15, and is generated by the pilot flames, the main burner. maybe readilv started, by opening the needle valve 24 o the casing 20, which will cause the vaporized fuel to be injected into the bottom portion of the main body or casing, and at the same time, air "will'be drawn into and through the mixing tube 10 with the fuel to commingle with the fuel under the diaphragm orpartition 7. It is evident that the air and fuel in being forced under the diaphragm-7, will cause the same] to thoroughly admix, the diaphragm 7 also serving as a spreader for the mixture. The

gaseous mixture will then pass upwardly through the opening 9 and'along the various corrugation or ridges 2 to passy'up wardly, through the slots or outlets 4: for supporting the main flames throughout the area of the main burner. After-the auxiliary or pilot burner has been started, the

same may be operated continually, whereby the main burner may be broughtinto and out of operation, at will, and without the necessity of priming the mainflburner' by hand, and without the necessity of igniting i the gas by hand. It is possible, however, to shut off the auxiliary or pilot burner during the operation of the main burner, the auxiliary or pilot burner being readily started just prior to the shutting 01f of the main burner, if desired, in order that the main burner may be readily started at a subsequent time.

From the foregoing, taken in connection attributes of the present invention will be obvious to those versed in the art without further comment being necessary,

Having thus described the invention, what is claimed as new is 1. A burner embodying a casinghaving upper outlets, a diaphragm within the easing andextending to the-sides andone end thereof, there being an opening between the other end of the casing and diaphragm, and a mixing tube carried by the last mentioned end of the casing and projecting under the diaphragm.
